Shutdown-Mode Bits (PD_0, PD_1)
Use the shutdown-mode bits and control bits to
shut down each DAC independently. The shutdown-
mode bits determine the output state of the selected
channels. The shutdown-control bits put the selected
channels into shutdown mode. To select the shutdown
mode for DACA–DACD, set PD_0 and PD_1 according
to Table 8 (where “_” is replaced with one of the select-
ed channels (A–D)). The three possible states for unity-
gain versions are 1) normal operation, 2) shutdown with
1k
output impedance, and 3) shutdown with 100k
output impedance. The three possible states for force-
sense versions are 1) normal operation, 2) shutdown with
1k
output impedance, and 3) shutdown with the output
in a high-impedance state. Table 9 shows the com-
mands for writing to the shutdown-mode bits. Table 10
shows an example of writing the shutdown-control bits.
This command shuts down DACA with 1k
to ground
and shuts down DACB–DACD with 100k
to ground.
Always write the shutdown-mode-bits command first and
then write the shutdown-control-bits command to proper-
ly shut down the selected channels. The shutdown-
control-bits command can be written at any time after the
shutdown-mode-bits command. It does not have to
immediately follow the shutdown-mode-bits command.
Settling-Time-Mode Bits (SPD_)
The settling-time-mode bits select the settling time (FAST
mode or SLOW mode) of the MAX5580–MAX5585.
Set SPD_ = 1 to select FAST mode or set SPD_ = 0 to
select SLOW mode, where “_” is replaced by A, B, C, or
D, depending on the selected channel (Table 11). FAST
mode provides a 3μs maximum settling time, and SLOW
mode provides a 6μs maximum settling time.
